Abstract (en)
[origin: US5230726A] An improved method for the continuous fabrication of filter units for use in automotive air bag inflators by spirally winding a hollow cylindrical core, at least one filter layer, and an outer layer to form a continuous spirally wound filter unit. The continuous spirally wound filter unit is then cut into individual filter unit of desired length by the use of conventional cutting device.
